So, let’s proposed a new rule of thumb for the required ARC/L2ARC size for a a given dataset:
  • Recordsize of 128KB => 0.1% of the uncompressed dataset size
  • Recordsize of 64KB => 0.2% of the uncompressed dataset size
  • Recordsize of 32KB => 0.4% of the uncompressed dataset size
  • Recordsize of 16KB => 0.8% of the uncompressed dataset size
